PAPER-CUTTER.

SPEGIFIGATION forming part of Letters Patent No. 745,517,

dated December 1, 1903.

Application filed May 13, 1903. Serial No. 156,916. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE IV. PEBKS, a citizen of the United States,residingat Springfield,in the county of Clark and State of Ohio,

have invented certain new and useful Improvements in Paper-Cutters, of which the following is a specification.

, My invention relates to paper-cutters; and the object of the invention is to provide a sim- IO ple and effective paper-cutter which can be economically constructed and effective in operation.

In the accompanying drawings, Figure l is a perspective view showing a cutter embody- [5 ing the invention mountedion a straight-edge ready for use. Fig. 2 is a perspective view of the same detached and shown from the rear. Fig. 3 is a sectional view, and Fig. 4 is a side elevation.

Like parts are represented by similar letters of reference in the several views.

- In constructing my improved cutter I employa main frame a, in which is mounted in a suitable manner a rotary cutter b, the frame a. being provided with a handle a at one end and with a downwardly-projecting flange a at the other.

A straight-edge e is provided, (shown in Fig. 1,) having a groove 6'. The straight-edge is 0 also preferably provided with a metal cornerpiece 6 which forms a wearing and guiding surface, and this metal corner-piece e projectg. over a portion of the groove, as shown at e To the rear of the main frame of the cutter is attached a guide or gage block 0 through the medium of a stud c, and mounted on the stud c is a roller (1. The gage-block is also extended downwardly and has secured there- 40 to beneath the roller d guiding-rolls d and 01 which operate in connection with the flanged part c of the straight-edge to support and guide the frame. A forwardly-projecting fiat spring 0 is attached to the gage-block c, as shown, and extends forwardly and upwardly and contacts with a lug or projection on the frame.

The operation of the device it is thought will be readily understood. The gage part 5o of the block is slipped into the groove of the straight-edge with the roller d on top thereof and the rollers d and at under the overhanging flange. A downward. pressure on the handle ct will cause the frame to tilt on the stud 0', so as to bring the knife in contact with the material to be cut, this downward movement operating against the spring 0 which will return the frame and knife to normal position. By employing the rollers d, d, and d a very close adjustment can be secure and at the same time obviate the friction usually resulting from the close fitting of the parts on the straight-edge. By having the gage-block connected to the frame solely by the stud c, which also forms the arbor for the roller d, I provide an extremely simple construction anddispense with the multiplicity of parts and at the same time produce a very effective and easily-operated cutter.

Having thus described my invention, 1 claim- 1 1. A main frame and a rotary cutter mounted thereon, a gage-block, a roller between said frame and gage-block, a stud for connecting said frame and gage-block through said roller, and a spring between said gage-block and frame, substantially as specified.

2. The combination with the frame and rotary cutter, of the gage-block, a spring attached thereto,a projection on said frame contacting with said spring, a roller mounted on a stud which also serves to connect said frame and gage-block, and auxiliary rollers below said main roller, substantially as and for the purpose specified.

3. Thecombinationwiththerecessedframe, of a rotary cutter mounted therein, a depending flange on said frame, a recessed gageblock, a roller mounted in said recessed gageblock, a stud passing through said roller and forming a connection for said gage-block and frame, a forwardly-projectin g spring secured to said gage-block and contacting with said frame, and auxiliary rollers also mounted on said gage-block below said main roller, sub stantially as specified.

In testimony whereof I have hereunto set my hand this 8th day of May, A. 11-1903. GEORGE W. PERKS. Witnesses;
